Detailed Description

Groups multiple QCPBars together so they appear side by side.

When showing multiple QCPBars in one plot which have bars at identical keys, it may be desirable to have them appearing next to each other at each key. This is what adding the respective QCPBars plottables to a QCPBarsGroup achieves. (An alternative approach is to stack them on top of each other, see QCPBars::moveAbove.)

Usage

To add a QCPBars plottable to the group, create a new group and then add the respective bars intances:

Alternatively to appending to the group like shown above, you can also set the group on the QCPBars plottable via QCPBars::setBarsGroup.

The spacing between the bars can be configured via setSpacingType and setSpacing. The bars in this group appear in the plot in the order they were appended. To insert a bars plottable at a certain index position, or to reposition a bars plottable which is already in the group, use insert.

To remove specific bars from the group, use either remove or call QCPBars::setBarsGroup(0) on the respective bars plottable.

To clear the entire group, call clear, or simply delete the group.

Member Enumeration Documentation

◆ SpacingType

enum QCPBarsGroup::SpacingType

Defines the ways the spacing between bars in the group can be specified. Thus it defines what the number passed to setSpacing actually means.

See also: setSpacingType, setSpacing

Enumerator
stAbsolute	Bar spacing is in absolute pixels.
stAxisRectRatio	Bar spacing is given by a fraction of the axis rect size.
stPlotCoords	Bar spacing is in key coordinates and thus scales with the key axis range.

Definition at line 5673 of file qcustomplot.h.

Constructor & Destructor Documentation

◆ QCPBarsGroup()

QCPBarsGroup::QCPBarsGroup ( QCustomPlot * parentPlot )

explicit

Constructs a new bars group for the specified QCustomPlot instance.

Definition at line 24008 of file qcustomplot.cpp.

Member Function Documentation

◆ append()

void QCPBarsGroup::append ( QCPBars * bars )

Adds the specified bars plottable to this group. Alternatively, you can also use QCPBars::setBarsGroup on the bars instance.

See also: insert, remove

Definition at line 24080 of file qcustomplot.cpp.

◆ bars() [1/2]

QList< QCPBars * > QCPBarsGroup::bars ( ) const

inline

Returns all bars currently in this group.

See also: bars(int index)

Definition at line 5691 of file qcustomplot.h.

◆ bars() [2/2]

QCPBars * QCPBarsGroup::bars ( int index ) const

Returns the QCPBars instance with the specified index in this group. If no such QCPBars exists, returns nullptr.

See also: bars(), size

Definition at line 24050 of file qcustomplot.cpp.

◆ clear()

void QCPBarsGroup::clear ( )

Removes all QCPBars plottables from this group.

See also: isEmpty

Definition at line 24067 of file qcustomplot.cpp.

◆ contains()

bool QCPBarsGroup::contains ( QCPBars * bars ) const

inline

Returns whether the specified bars plottable is part of this group.

Definition at line 5696 of file qcustomplot.h.

◆ getPixelSpacing()

double QCPBarsGroup::getPixelSpacing	(	const QCPBars *	bars,
		double	keyCoord
	)

protected

Returns the spacing in pixels which is between this bars and the following one, both at the key coordinate keyCoord.

Note: Typically the returned value doesn't depend on bars or keyCoord. bars is only needed to get access to the key axis transformation and axis rect for the modes stAxisRectRatio and stPlotCoords. The keyCoord is only relevant for spacings given in stPlotCoords on a logarithmic axis.

Definition at line 24234 of file qcustomplot.cpp.

◆ insert()

void QCPBarsGroup::insert	(	int	i,
		QCPBars *	bars
	)

Inserts the specified bars plottable into this group at the specified index position i. This gives you full control over the ordering of the bars.

bars may already be part of this group. In that case, bars is just moved to the new index position.

See also: append, remove

Definition at line 24103 of file qcustomplot.cpp.

◆ isEmpty()

bool QCPBarsGroup::isEmpty ( ) const

inline

Returns whether this bars group is empty.

See also: size

Definition at line 5694 of file qcustomplot.h.

◆ keyPixelOffset()

double QCPBarsGroup::keyPixelOffset	(	const QCPBars *	bars,
		double	keyCoord
	)

protected

Returns the pixel offset in the key dimension the specified bars plottable should have at the given key coordinate keyCoord. The offset is relative to the pixel position of the key coordinate keyCoord.

Definition at line 24168 of file qcustomplot.cpp.

◆ registerBars()

void QCPBarsGroup::registerBars ( QCPBars * bars )

protected

Adds the specified bars to the internal mBars list of bars. This method does not change the barsGroup property on bars.

See also: unregisterBars

Definition at line 24144 of file qcustomplot.cpp.

◆ remove()

void QCPBarsGroup::remove ( QCPBars * bars )

Removes the specified bars plottable from this group.

See also: contains, clear

Definition at line 24123 of file qcustomplot.cpp.

◆ setSpacing()

void QCPBarsGroup::setSpacing ( double spacing )

Sets the spacing between adjacent bars. What the number passed as spacing actually means, is defined by the current SpacingType, which can be set with setSpacingType.

See also: setSpacingType

Definition at line 24039 of file qcustomplot.cpp.

◆ setSpacingType()

void QCPBarsGroup::setSpacingType ( SpacingType spacingType )

Sets how the spacing between adjacent bars is interpreted. See SpacingType.

The actual spacing can then be specified with setSpacing.

See also: setSpacing

Definition at line 24028 of file qcustomplot.cpp.

◆ size()

int QCPBarsGroup::size ( ) const

inline

Returns the number of QCPBars plottables that are part of this group.

Definition at line 5693 of file qcustomplot.h.

◆ unregisterBars()

void QCPBarsGroup::unregisterBars ( QCPBars * bars )

protected

Removes the specified bars from the internal mBars list of bars. This method does not change the barsGroup property on bars.

See also: registerBars

Definition at line 24157 of file qcustomplot.cpp.
